Abstract
Abstract A traffic barricade is constructed of disposable material such as cardboard and is formed of a single flat sheet of material formed into separate sheets by folding along a predetermined line. The fold forms a first and second sheet of material, each having a pair of scorelines, the first of which defines a border of a vertical area and the second of which forms a border of a horizontal area when the barricade is erected. The flat sheets each have a sloping surface between the score lines when the barricade is erected. The vertical areas of the two flat sheets formed by the folding of the single flat sheet are permanently secured to each other. The horizontal areas of each of the two flat sheets extend toward one another and one of the horizontal areas extends between the sloping surfaces of the sheets to maintain the sheets in spaced apart relation at the horizontal areas. One of the horizontal areas includes foldable edges that can be erected to an upright position to form a tray for receiving dirt or other ballast materials to anchor the barricade when it is in place.

Claim 1
Independent Claim
291 words
A disposable traffic barricade comprising: a. a first flat sheet of foldable material having a first scoreline for folding in a first direction and a second scoreline for folding in a second direction, said first scoreline forming a border of a vertical area, said second scoreline forming a border of a horizontal area when said barricade is erected; b. said first flat sheet having a sloping surface between said scorelines when said barricade is erected; c. a second flat sheet of foldable material having a first scoreline for folding in a first direction and a second scoreline for folding in a second direction, said first scoreline forming a border of a vertical area, said second scoreline forming a border of a horizontal area when said barricade is erected, said horizontal area extending toward the horizontal area of said first flat sheet; d. said second flat sheet having a sloping surface between said scorelines when said barricade is erected; e. means permanently securing the vertical areas of said first and second sheets in back-to-back contact with each other with the reflective material thereon facing in opposite directions; f. one of said horizontal areas extending between and in contact with the sloping surfaces of said first and second sheets to maintain said second scorelines in predetermined spaced apart relation; and g. one of said horizontal areas including edge adjacent areas foldable to an upright position to form a tray having said horizontal area on the bottom, having the sloping surfaces of said flat sheets on the ends, and having said edge adjacent areas folded to an upright position on the sides, thereby to provide a receptacle for receiving dirt or other ballast material to anchor said barricade against wind and other such forces.
